it wont my civic had a better tranny than the g one thing ive learned from the bmw is once youve upgraded bushings removed cdv and got a short shifter it will feel like a new tranny i hope the same can be said for the g after some cash i should probably note that my e is the m not the s which i think will be just as reliable just not as cheap to maintain basically the g will be much cheaper to maintain with less headaches and the m will be so much more fun to drive with the occasional coin being dropped if i had to choose id get the m but i like working on cars my bmw has been perfect so far i was expecting hell
